GLU_DISPLAY_MODE = 100204,

Discovered DISPLAY_DEVICE struct defined with CharSet=CharSet.Ansi. Works much better on Win7 with CharSet=CharSet.Auto. Suspect this is also true of a number of other structs and Win7 predecessors.

Hide the Start button icon on the navigation bar. When the Start icon is hidden, the shell is in a special state in which clicking or tapping the navigation bar will not display the drop-down Start menu. The navigation bar is essentially disabled when in this state. While in this mode, WM_LBUTTONDOWN and WM_LBUTTONUP messages will be forwarded to hwndRequester. This allows an application to drop out of this mode by calling this function with the SHFS_SHOWSTARTICON, when the user clicks or taps the navigation bar.

A request to display the input panel. Any pending SIP_DOWN requests are ignored.
